Bogus SqlParser warning for valid ALTER TABLE .. MODIFY COMMENT syntax

[lukaseder]

Steps to reproduce

try (Statement s = connection.createStatement()) {
    try {
        s.executeUpdate("create table t (i int, primary key (i)) engine = MergeTree()");

        try (PreparedStatement p = connection.prepareStatement("alter table t modify comment 'comment'")) {
            System.out.println(p.executeUpdate());
        }
    }
    finally {
        s.executeUpdate("drop table if exists t");
    }
}

The query uses valid syntax and works well on the server:
